Updates to actionable genes page

- Only show treatment with FDA level. If the treatment is Dx/Px, then the fda level is not available
- Add key to actionable genes page. Multiple tables will be rendered if the key is different. This helps to differentiate the paginated vs non-paginated tables. The react-table lib has issue recognizing remove props.
